SPECIFICATION forming part of Letters Patent No. 658,501, datedSeptember 25, 1900.

Application filed January 11, 1900. Serial No. 1,056. (No model.)

To all whont it may concern.-

Be it known that I, ALBERT BOYD HUNN, a citizen of the United States,residing at Bristol, in the county of Hartford and State of Connecticut,have invented new and useful Improvements in Bells, of which thefollowing is a specification.

The present invention relates to bells, and more particularly to abellfor bicycles and [0 like vehicles; and its object is to produce abell ofsimple construction in the class of what has been termed double-strokebellsthat is to say, a bell which by a single pressure of a lever may bemade to give forth two sharp and distinct sounds.

To this end the present invention consists of the devices andcombination of devices which will be hereinafter described and claimed.

The present invention in one of its forms is illustrated in theaccompanying drawings, in

which Figure 1 is a perspective View of the bell attached to thehandle-bar of a bicycle, with a portion of the gong broken away, so asto show the arrangement of the parts. Fig. 2

is a plan view of the bell with gong removed,

the dotted lines on the left indicating the po-' sition of the strikerin the act of impinging against the gong and on the right the positionof the parts after pressure upon the lever.

Fig. 3 is a like plan view of the striking mechanism viewed from belowafter the lever has been actuated in one direction. Fig. 4 is a view indetail of the striker. Fig. 5 is a side view in detail of the striker;and Fig. 6 is a plan View of the lever, springs, and strikermount withthe striker removed.

Similar letters of reference represent corresponding parts throughoutthe views. 40 In the accompanying drawings the letter Ct designates thebase-piece, which may be provided with any one of the usual means ofattachment to the handle-bar of the bicycle or other support.

b is the gong, also of any usual desired form, size, material, andconstruction. A post 0, fixed, preferably, in the center of the base, isshown to support the gong, which may be secured thereto by ascrew-thread or any other suitable means.

01 is a lever pivoted to the base-piece, as at e.

This point is preferablylocated as near as pos sible to thecircumference of the gong, both for convenience in manufacture and forobvious advantages in use. A spiral spring f, with one end bent into ahole in the lever at g and the other coiled or bent around a post at 9,holds the lever firmly in its normal position and returns it theretowhen pressure upon the finger-piece d is removed.

My invention is represented in the drawings as embodied in abicycle-bell. It is equally adaptable to embodiment in a bell for anyother appropriate use, in which event the outside end of the lever maybe provided with a means for attaching thereto a rope or crank or anyother means to actuate the same. The inner end of the lever is providedwith slots and channels to'limit and control the motion of the lever,striker-mount, and striker. 7o d 'on the right and d on the leftmaintain the striker in its proper position upon the lever. d is a slotor channel in which the strikermount rides and which permits a limitedplay in a right and left direction.-

d is a slot which, in the embodiment illustrated in the drawings, isused to limit the backward-and-forward motion of the lever, the centralpost projecting through the same and the sides of the slot striking thecentral post according as the lever is driven in one direction or theother.

A double-ended striker k, with right-hand striking-point 7c andleft-hand striking-point k is maintained upon the lever by thestrikermount m. This is constructed in any suit able way to maintain thestriker in place upon the lever and, as shown, is maintained in avertical position by shoulders y y upon the post h. The aperture to inthe striker, through which the post It passes, is enlarged, so as topermit horizontal play to the striker to a limited extent. A smallsprings, coiled about the post it and bearing upon a washers, may beused in a familiar manner to hold the striker in place and prevent noiseand rattling in operation.

r is a wire spring, coiled around a post 0" at one end, which ispreferably located upon the base substantially opposite the post c,which carries the lover. The spring at the other end is coiled looselyaround the post It.

it in that position.

This spring is either bent into a semicircular form or formed with oneor more intermediate coils in such a manner as todrive the strikermountto its extreme limit of motion in either the right or left handdirection as the lever moves the striker-mount past a point substantially central of the bell and to maintain i The operation of myimproved bell is as follows: The mechanism is shown in normal po- 1sition in full lines in Fig. 2. In thisinstance the spring f is holdingthe lever to its extreme left position. Apressure upon the finger-pieced will move the posterior end of the lever, carrying the striker pastwhat I calli the center of equilibrium and drive the said end of thelever toward the right position, as shown in dotted lines. When thelever is past the center, the coiled spring 0'- will become eifectiveand aid in driving theg le er toward the right position and at the{ sametime will throw the striker-mount m; sharply toward the right side ofthe slotd. Q Thereupon the striker 7c will spring forward, on account ofthe'impet-us thus given it tothe limit of play which it has upon thestrikeri mount m by reason of the elongated slot w and will impingeagainst the gong, imanediately recoil, and beheld in a non-contactposition by forccof the small spring and washer s s. Thereupon thepressure n pon ,lhe fingerpiece (1' being releasedi-he spri ng f will retractthe lever to its extreme left position, when the striker will be causedto impinge upon the gong upon that side in a siin-ilar manner.

It will be observed that this bell can be used as a single-stroke bell,a double-stroke bell, and by a rapid manipulation of the lever d it willbe made to produce a sound very similar to that of a so-calledelectric-stroke bell. I have found in practice that a bell constructedin themanner described is exceedingly effective as well as pleasantinuse, and I call particular attention to the fact that difiiculties inmanufacture are overcome for the reason that the expenses for inspectionand adjustment are reduced to a minimum, the action is positive, and allparts can be manufactured in quantities and substantially automatically.The parts are thus all interchangeable and can be assembled rapidly andcheaply with positive and reliable results.

It is manifest that there are numerousmodifications as to form andarrangement which can be made in this mechanism without departing fromthe spirit of my invention, and I do not therefore limit myself to theexact form and arrangement above described, but

hold myself at liberty to make such modifi- 6o as described.

2. An alarm-bell consisting of a basepiece and gong, a lever-springactuated in onedi-i striker upon the striker-mount and the striker-mountupon the lever. p

3. An alarm-bellcomprisingin its construction base-piece and gong; anactuating-1ever; a striker-mount upon the lever, and 00- operating.means to permit control, and limit 5 its motion thereupon; a strikerupon the striker-mount and cooperatingmeansto permit, control, and limitits motion thereupon; a springito actuate the striker-mount in eitherdirect-ion to cause the striker to impinge against the gong; and meansto maintain the striker in normal non-contact with the gong.

4:. An alarm-bellconsistingof a base-piece and gong; a lever limited inits motion carrying a striker-mount, and provided with channelscooperating with projections upon said striker-mount so as to permit,control, and limit the motion of the striker-mount upon the lover; astriker upon the strikerniount with projections engaging channels uponthe lever and a slot cooperating with the shaft of the striker-mount 1opermit, control, and limit the motion of the striker npon thestriker-mount and lever, a spring to actuate the striker-mount sharplyin either direction and frictional means to hold the striker at restupon the striker-mount, all constructed combined, and arranged so that amovement of the lever in either direction will efiect a sharpimpingement of the striker against the gong and exceptat the moment ofcontact maintain the same in normal noncontact with the gong.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
